Social network Snapchat made a name for itself by letting you share photos and videos that self-destruct in just a few seconds. That is, the app lets you impose a finite lifespan on your shares so they can be viewed for only a few seconds before being automatically deleted beyond retrieval.
While there’s certainly an argument that the seconds-long lifespan aspect is useless, Snapchat’s immense popularity, especially with teenagers and young adults, suggests otherwise. Apparently, there are a lot of people out there who love the idea of sending out secret photos and videos, without leaving any evidence of ever having done so. Just be warned that, despite Snapchat’s best efforts, there are ways for others to save what you send them, either using an app or just by snapping a screenshot.
